A cargo ship with 900 tons of coal sank off north-central Vietnam after a collision with an oil tanker Monday night.

The ship, owned by coal trading company Duong Cam, weighing nearly 1,000 DWT, and carrying the coal from the northern province of Quang Ninh to the company in Nghe An Province, sank at around 7:45 pm after crashing into the tanker which was leaving Nghe An.

All eight crew members were rescued after a four-hour effort and brought to shore the next morning.
